PURPOSE:To determine a natural pause insertion position by discriminating whether a pause should be inserted to a word boundary or not based on the numerical value which corresponds to the part of speech of the word of the boundary of each word constituting a sentence expressed with an inputted character string and indicates the preliminarily stored degree of easiness of pause insertion just after each word. CONSTITUTION:The character string to be converted to a voice is inputted from a character string input terminal 11. The inputted character string is sent to a morpheme analyzing part 12, and the sentence expressed with the input character string is divided to word strings, and parts of speech and readings of respective words are determined. A pause insertion position determining part 15 reads out the pause insertion probability which corresponds to the part of speech of the word just before the boundary of each word string having a part of speech and is stored in a pause insertion settlement storage part 14. The read-out pause insertion probability and the length of each word calculated by a word length calculating part 13 are used to determine the pause insertion position, and the result is outputted from a pause insertion position output terminal 16. Thus, the natural pause insertion position is determined. |
